G.R. No. 123450. August 31, 2005
GERARDO B. CONCEPCION, Petitioner, vs. COURT OF APPEALS and MA. THERESA ALMONTE, Respondent.

FACTS

Petitioner Gerardo B. Concepcion filed to annul his marriage to respondent Ma. Theresa Almonte on the ground of bigamy, alleging her prior subsisting marriage to Mario Gopiao. The trial court granted the petition, declaring the marriage void and Jose Gerardo, the child born during the void marriage, as illegitimate. It awarded custody to Ma. Theresa but granted Gerardo visitation rights. Ma. Theresa moved for reconsideration, arguing that a putative father of an illegitimate child has no legal right to visitation and that the child should use her surname, Almonte, not Concepcion.
The trial court denied her motion, invoking the “best interest of the child” principle under the Child and Youth Welfare Code. The Court of Appeals initially affirmed this decision. However, upon Ma. Theresa’s motion for reconsideration, the appellate court reversed itself. It ruled that since Ma. Theresa was legally married to Mario Gopiao at the time of the child’s birth, Jose Gerardo is presumed under Article 164 of the Family Code to be the legitimate child of that marriage, not the illegitimate child of Gerardo.

ISSUE

The core issue is whether Gerardo, as the biological father under a void marriage, can claim visitation rights and impose his surname on the child, Jose Gerardo, who is presumed legitimate to the mother’s first marriage.

RULING

The Supreme Court denied Gerardo’s petition and affirmed the Court of Appeals’ reversal. The legal logic rests on the conclusive presumption of legitimacy under Article 164 of the Family Code. A child conceived or born during a valid marriage is presumed legitimate. Since Ma. Theresa’s marriage to Mario Gopiao was never annulled and was subsisting when Jose Gerardo was born, the child is conclusively presumed to be the legitimate child of Mario Gopiao. This presumption can only be contested in a direct proceeding filed for that purpose by the proper parties, which Gerardo did not institute.
Consequently, Gerardo has no parental authority or legal right to visitation over a child who is, in the eyes of the law, the legitimate child of another man. Granting such rights would disrupt the child’s status and the integrity of the legitimate family unit. Furthermore, the child cannot use Gerardo’s surname, as he is not considered Gerardo’s illegitimate child. Any change of surname would require a separate proceeding initiated by the child, represented by his mother, under Rule 103 of the Rules of Court, and must be justified by the child’s best interest, which was not established here. The Court emphasized that while the child’s welfare is paramount, it cannot be invoked to contravene established legal presumptions that safeguard the child’s legitimate status and family solidarity.
